Dream About Defending Sister In Fight

I was at my big sisters place. She had her ex staying with her, he was handicapped. (He isn’t irl). Anyway, I was sleeping in a bed and I was supposed to take care of her kid for a little bit. While she was doing stuff. So I had to get up in the morning and drive him to kindergarten. In the middle of the night, the kid woke me up and I was so scared that I was late but it was 1:30 am. So I played a bit with him until I had to bring him to kindergarten. My problem was that I had to be at school as well, around the same time but even though it was probably more important, I chose to help my sister. Then suddenly one of our elder cousins came by? We never talk or meet. But she was so rude, talking to me about how my sister was messy and didn’t know what she was doing. So I beat her up. Violently. I punched her in the face so many times and absolutely went crazy telling her to never say that ever again. Also “I don’t understand why everyone says that, it’s not true!” Defending my sister as I beat up our cousin. I had to bring my sisters kid out of the fight, so I went to the kitchen and gave my sister her kid then proceeded to fight our cousin. In the end she went away because I didn’t give in to bullshit like that.
